Kiwi Vines are very aggressive growers. This article states they don't grow quickly. Vines will grow several inches a day at each growing tip. It takes very aggressive pruning to control their size. Kiwi roots are similar to hop roots in that they get very fat and long very quickly. I would say you need to prune them at least monthly after flowering. The cold hardy kind take about 6 years to fruit. They are EXTREMELY sensitive to frost, despite them being called "arctic kiwi"
